RESUMO
OBJECTIVE: To investigate whether risk factor-based screening in pregnancy is failing to identify women with hepatitis C virus (HCV) infection and to assess the cost-effectiveness of universal screening. DESIGN: Retrospective study and model-based economic evaluation. SETTING: Two urban tertiary referral maternity units, currently using risk factor-based screening for HCV infection. POPULATION: Pregnant women who had been tested for hepatitis B, HIV but not HCV. METHODS: Anonymised sera were tested for HCV antibody. Positive sera were tested for HCV antigen. A cost-effectiveness analysis of a change to universal screening was performed using a Markov model to simulate disease progression and Monte Carlo simulations for probabilistic sensitivity analysis. MAIN OUTCOME MEASURES: Presence of HCV antigen and cost per quality-adjusted life year (QALY). RESULTS: In all, 4655 samples were analysed. Twenty had HCV antibodies and five HCV antigen. This gives an active infection rate of 5/4655, or 0.11%, compared with a rate of 0.15% in the risk-factor group. This prevalence is 65% lower than a previous study in the same hospitals from 2001 to 2005. The calculated incremental cost-effectiveness ratio (ICER) for universal screening was 3,315 per QALY gained. CONCLUSION: This study showed that the prevalence of HCV infection in pregnant women in the Dublin region has declined by 65% over the past two decades. Risk factor-based screening misses a significant proportion of infections. A change to universal maternal screening for hepatitis C would be cost-effective in our population. TWEETABLE ABSTRACT: Universal maternal screening for hepatitis C is cost-effective in this urban Irish population.

BACKGROUND: We investigated the real-world effectiveness of interferon-free regimens for the treatment of patients with compensated cirrhosis infected with hepatitis C virus (HCV). METHOD: Using the Irish national HCV treatment registry, the effectiveness and safety of interferon-free regimens for HCV-infected patients treated between April 2015 and August 2016, was determined. RESULTS: A SVR12 was achieved in 86% of subjects treated with sofosbuvir/ledipasvir ± ribavirin (SOF/LDV±RBV), 93% treated with paritaprevir, ombitasvir and ritonavir combined with dasabuvir ± ribavirin (3D±RBV) and 89% treated with sofosbuvir/daclatasvir ± ribavirin (SOF/DCV±RBV). The discontinuation rate was 5% and the on-treatment mortality rate was 1%. CONCLUSION: The availability of interferon-free regimens represents a significant breakthrough for the treatment of HCV infection. Treatments options, with high SVR12 rates, are now available for patients with compensated cirrhosis who were unsuitable for treatment with interferon-based regimens. Data obtained from studies conducted in real world practice provide robust information fundamental for input into future economic evaluations for agents used for the treatment of HCV infection.
